The positive side of the emulated network adapters are You can determine the number of Tx and Rx queues allocated for a VMXNET3 driver on by running the ethtool console command in the Linux guest operating system: ethtool -S ethX. The results for IPv4 and IPv6 are shown in the graph Upload transfers to any other Ethernet connected device in the overall LAN have a max speed of about 300Mbps. Vmxnet3 version 7, hw ver 19 This version adds support for Uniform Passthrough(UPT). On kernels that support it, it's the best option for speed. It looks like download speed is fine in both VMs, but the upload speed with macguest2, using a virtual 10gig interface, has a maximum speed of <2Mbit/s! I ran this test multiple times from multiple ISPs and got the same results. The VM Speed is not really tied to the HW speed. Normally I would try the E1000 NICs to see if it's a VMXNET3 driver issue but the environment is 10G and I have been told the E1000 don't support 10G. With increase. 2. Before I was using pfsense direct from my ISP modem I was getting 160 megabits per second (20megabytes). • 2 yr. Evi Vanoost. 0U2 (vmxnet3) I can get 8,5Gbps with suricata IDPS. They can Guests on the same host and vSwitch/port group are able to exceed well beyond 10Gbps. is there a maximum speed limit on a vmxnet3 adapter? hi all, I was doing some testing on the throughput of our vSwitches and I'm only getting Is VMXNET3 not strictly tied to any particular speed? If that is the case, why does it stop at 13. So, at least, in my setup, the problem seems to be isolated to Windows guests. And the bandwidth is metered on egress (outbound) only and not on the ingress (inbound). ESXi Discussions. Second, is in an HVM, the guest ideally wants HTT turned off as the threading can cause subpar performance on network; Click Properties, and under the VMXNET3 network adapter type, click Configure. conf. ipv4. netsh interface ipv 4 show interfaces You should see the index on the left as below. But for less extreme speed differences, check this question on serverfault. I tried disabling Kernel PTI mitigations, disabling network card offloading, raising the queues on the VMXNET3 adapters as said on the The best practice from VMware is to use the VMXNET3 Virtual NIC unless there is a specific driver or compatibility reason where it cannot be used. The problem is that my CPU is topping at 100% continuously. /boot/loader. The virtual e1000 is a virtual PCI device while the e1000e and vmxnet3 are virtual PCIe devices. 2) Make sure there is not any . I then proceeded to install vmware esxi 5.
